Application filed February 15, 1917. Serial No. 148,712.

To all whom it may concern:

Be it known that I, Howxnn M. Dunner, a citizen of the United States,and a resident of lhilm'lelphia, in the county of Philadclphia and Stateof Pennsylvania, have invented certain new and useful Improvements inDyeirig-Machines, of which the following is a specification.

My invention relates to a dyeing machine and refers particularly to amachine adapted for the dyeing of textile fibers compressed within adyeing chamber, the dyeing being accomplished by the forced passage ofthe dye liquor through the fiber mass.

Among the objects of my invention is a dyeing machine particularlysuitable for the dyeing of warps in the ball, whereby the condition ofthe fiber may be accurately and readily judged at any stage of thetreatment without opening the dyeing chamber and whereby even resultsmay be obtained without disturbing the fiber to be dyed.

Another object of my invention is a dye ing machine in which the dyedgoods may be after-treated with water, steam, air, or other materials orsubstances without han- (lling the dyed goods.

Other objects of my invention will be evident upon a consideration of myspecification and claims.

I have found that the even or uneven dyeings results obtained in amachine of this general character depend largely upon the particularshape of the openings through which the dye liquor enters the fibermass, and that unevenness can be prevented by the use of o 'ienings of aparticular shape, the conformation of which enables the liquor to spreaditself through the fiber mass without the formation of channels of How.

I have further found that this desirable result can be obtained if thefiber-mass is supported in the dyeing chamber upon a series oftransverse grate-bars.

I have further found that the evenness of the dyeings and treatments maybe enhanced by inclosing the fiber in a series of containers and passingthe treating liquid through these containers and the fiber containedtherein.

In the use of many dyestuffs it is necessary after dyeing to treat thedyed goods with water for washing purposes, or with solutions ofchemicals such as metallic salts or oxidizing products, for the purposeof after-treatment, or with oxygen or air for oxidizing or dryingpurposes. In the following of these after-treatments it is essentialthat every portion of the dyed goods be thoroughly and uniformly treatedand that the operation be performed as readily and quickly as possible.All of these results are obtainable by the use of the device of myinvention, in which the goods are placed in the dyeing chamber and thenrapidly, easily and completely dyed and after-treated without furtherhandling of the goods and without the formation of channels by theliquids employed. The device therefore insures even and uniform resultswith a minimum of time, labor and expense.

One form of my device is shown in the accompanying drawings in whichsimilar parts are designated by similar numerals.

Figure 1 is a side view of one form of my invention, partly broken awayto disclose a portion in cross-section.

The outer portion of the dyeing machine, as illustrated, comprises theupwardly converging cover 12 removably attached to the member 13 by thescrew bolts 14. ll, the member 13 being movably attached to the shell 15by means of the screw bolts 16, 16, the shell 15 being attached to theshell 17 by the bolts 18, 18, the shell 17 being attached to thedownwardly converging shell 1%) by the bolts 20, 20, the shell 19 beingattached to the centrifugal pump 21 by the bolts 22, 22. The pipe 23connects the chamber of the pump 21, with the three-way pipe 2-l-, thelatter having the pipes 25, 2G and 27 fitted respectively with thevalves 28, 29 and 30. The pipe 25 is connected with an air cornpressornot shown; the pipe 26 opens into the air and the pipe 27 may beconnected with a drain or receptacle as desired. The pump 21 isconnected with the pipe 31, which in turn is connected with the pipe 32,

the latter being connected with the pipe carrying the valve 3%, the pipecarrying the valve 36 and the pipe 37 carrying the valve 38.dye-dissolving tank, not shown, the pipe 35 is Connected with aliquor-reserve tank39, and the pipe 37' is connected with a watersupply. I H 1 Y The object of the reserve tank 39 is to allow of theproduction and use ofa larger quantity of .dye liquor than is necessaryto fill the dyeing device. strength of the dye-liquor may be governed tomeet the r quirements of each individual dyeing operation, and thellquidmaintained in a condition where the dye will not be precipitatedupon the fiber. It also allows a o more uniform supply of liquor to thepump 21;.

The member 13 is of angular shape one.

: bars 17, 17, allowing the series of openings 19, 19 between thegrate-bars. A series of upwardly extendinglugs 70, 70 are fixedlyattached to the outer periphery of the bottom of the tray 4-6, and anannular imperforate side member 71 integral with the gratebars a, 17extends upwardly to the top of the lugs't'O, 70, said side member 71being integral with and fixedly attached to the interior faces of thelugs 70, 70.

The lugs 70, 70 are vertically movable within. the lug-chambers 72, 72of the shell 15. The interior of the fiber-tray 46 is therefore formedby the grate-bars 17, 47 and the annularside member 71.

The'device is provided with a number of removable fiber-trays 73, 74:,the construction of which is similar to that of the tray 16, each traybeing capable of a position over and upon the tray beneath it. A similartray 88 is used as a top tray, no fiber being contained therein.

In orderto facilitate reference to the various chambers, they willhereafter be referred to as the top chamber 51, the liquor-supplychamber 53, and the lower chamber A sample dyeing machine 55 exactlysimilar to the one above described except that it is in smallerproportion and carries the threaded closed top 56 instead of the top 12,

is connected'tothe liquor-supply chamber 53 by the pipe 57 carrying thevalve 58. The up-perportionof the sample. machine .55 is The pipe 33 isconnected with a By this means the connected with a pipe 59, capable ofbeing revolved into the position shown by the dotted line 60. i A pipe61 connects the thermometer 62 with the liquor-supply chamber 53, thepipe 61 being extended beyond the thermometer ito the' pipe 63, capableof being revolved into the position shown by the dotted line 6 1.

A perforated steam pipe 65 is within the liquor supply chamber The topchamber 51 contains a series of minted plates 66, 66, extending acrossthe chamber. are situated within the lower chamber 54:, and a series ofsimilar plates 75, 75 are situated within the chamber of the pump 21.

I T he operation of the device is as follows r The top 12, the member 13and the fibertrays 68,73 and 74. are removed. The fibertray 4-6 properlypacked with the fiber to be treated, and the fiber-trays 73-and 7%,which have been previously packed with the fiber, are'placed thereon andthe tray 88.

A series of similar plates 68, 68,

firmly upon each other. Goods are similarly placed in the sample device55. V .Valves 1.5, 28, 29, 30, 3S and 3 1 are closed and valves 58, 453and 36"are opened, and the pipes 59 and 63 situated asshovvn by thedotted lines 60 and 61-. The necessary dye'stu'tlihaving been dissolvedin the d ye dissolving tank, not shown, connected with the pipe 33, thevalve 34: is opened and the centrifugal pump 21 is started.- The pump 21forces the dye liquor upwardlybetween the plates 75, '7 5 and 68, 68, inthe chamber of the-pump and the bottom chamber 5 1, the liquor supplychamber 53, the foran'iinous bottoms of operation the dye-liquor isforced u nvardlv through the sample device 55 and the goods containedtherein The ten'iperature is varied by means or steam introduced throughthe steam-pipe 65 and the temperature deter mined by means of thethermometer 62-.v

From time to time, the valve is closed, the top of the samp e device 55rem ved and the goods contained there n examined to determine theircondition, and the top 56;

replaced and the valve 58 opened and the dyeing operation continueduntil a test (it the goods in the sample device shows them to beproperly dyed.

The next step is the removal of the dyeliquor contained in the device.This is accomplished by closing valves 43, SH- and 36, opening valve 30and stopping the pump '21. This allows all oil' the dye-liquor in thedevice to drain through the pipe J7 into a suitable receptacle fortuture use it desired.

The next step is that of washing the e.\' cess of dye-liquor from thegoods and this is aceonmlished by closing valve 30 and open- .ing valves38 and +15, and starting pump 21. This allows fresh water to enterthrough the pipes o7, 232 and 31. into the pump 21 which forces itupwardly through the device and the goods contained therein and throughthe overflow pipe l linto a drain.

The next step is that ol' oxidizing the dyeings, it oxidizable, by meansof air or of drying the goods. This is accomplished by placing the pipes59 and (33 in the position shown by the full lines, placing the top uponthe device, atlixing it thereto by means of the screw-bolts 1 l, H, andattachingthc upper open end of the top 12 to a vmauun or suction pump,not shown. The valves 45 and 38 are closed, the valve 9 is o 'iened. andthe pump 21, stopped. The vacuum or suction pump attaclual to the top 12thus draws air through the pipe it; upwardly through the device and thegoods contained therein. It the amount of air thus obtained isinsullicient tor the purposes desired, the valve 28 connecting the pipe25 with an air compressor may be opened and the valve 2!) closed andthus sullicicnt air may be obtained. It is evident that the air passingthrough the pipes 95 and 26 may be heated before its introduction intothe device, if desired.

The particular formation oi the 'l'oraminous bottoms of the fiber-traysttt. 73 and 74 and the tray 88 causes the dye liquor to be spread outand evenly distributed through the goods. causing even dveings, thesimilarity ot' the 't'oraminous bottoms causes a more regular pressureof the dye liquor within the fiber and the plate members ($6, (16: (38,(i8 and 75 intensity this distribution and regularity of pressure.

It is to be further noted that the goods are dyed, washed andattcr-treated or dried without handling. and that all ot the operationsare under exactly the same conditions, and that the condition of thegoods being dyed or treated can be dctermimal at anv time during theoperation \Wi-il1()llt interrupting the operation by ex mining the goodsin the sample device in the Modification. shown in Figs. 5. G and 7, the}')lD.l1S G8, 68 ot' Fig. l are replaced by plates similar to plate (37,the exterior of the device in this modili ation being preterablycircular and conical.
